Which is Which
Which law would we think of when we see the flames of a rocket shooting down so the rocket can go up?
The force that opposes motion between two surfaces in contact with each other.
Friction
Which of the following best describes the energy transformations that occur when a flashlight that runs on batteries is turned on?
chemical to electrical to radiant
An object at rests stays, an object in motion stays in motion
Born on a branch, I fell to earth,
But my descent gave a giant birth.
I hit no target, broke no skin,
Yet changed the state the world was in.
I launched a thousand cosmic thoughts,
Though I am bound to rot.
What am I?
You are carrying a lunch tray when you bump into the edge of a table. Although the tray did not tip, your milk falls off of the front of the tray.
1st Law
An object tendency to resist change in its motion is known as ____________
Inertia
A lamp’s light bulb, which is plugged into an electric outlet, draws energy which flows through a thin Tungsten wire in the bulb causing it to glow. Choose the correct energy transfer sentence.
Electric - Radiant - Thermal
For every action there is an equal and opposite reaction
Newton's Third Law
According to Newton's 3rd law - When a hammer strikes a nail, the nail does what in repsonse?
The nail strikes back at the hammer with the same amount of force but in an opposite direction
A person steps out of the boat and onto the dock. As the person moves forward onto the dock, the boat moves backward.
What law is best represented here?
3rd Law
the straight-line distance and direction from an object's starting point to its ending point.
Displacement
You and your friend, are playing tug of war. Your friend pulls with a force of 55 N, to the rights. You pull with a force of 65 N, to the left. What is the net force on the rope?
10 Newtons to the left.
When something has speed in a certain direction it is called ___________.
Velocity
Chemical Change
A truck that is travelling at a constant speed is carrying some boxes. If the truck comes to a sudden stop, what will most likely happen to the boxes?
The boxes will slide towards the front of the truck
I can be a sudden burst, a roaring, racing thrill,
Or the heavy, creeping brake that brings you to a still.
I am there when paths are straight, or when you twist and bend,
Changing how you travel from beginning to the end.
Acceleration
Identify the 4 step energy transformation that occurs in the journey of a modern solar-powered flashlight:
Nuclear (in the sun- fission)
- light/radiant (solar panels)
- chemical (battery)
- electrical/radiant/ thermal (generating light, heat)
_______________ is calculated by dividing the force exerted on an object by the mass of the object
Acceleration
I can be constant, yet I am always a change.
Without a direction, I still have a range.
The swiftest of runners will chase me in vain,
For I am the measure of what they sustain.
I am born from a distance divided by time,
A limit for light, and a ticket for crime.
What am I?
Speed
We are a royal trio, governing both the vast and small,
The reason why a rocket flies and why you do not fall.
The first demands resistance to a change in how you rest,
The second multiplies your mass to put your strength to test.
The third ensures each action has a twin that pushes back,
We rule the path of every wheel, of every wing and track.
Laws of Motion
I am the sum of all battles, though I never hold a sword,
If my rivals match exactly, stillness is my sole reward.
But if one side grows too strong, I will break the steady peace,
Causing objects to speed up, slow down, or suddenly cease.
What am I?
Net Force
I am the ghost in the machine that breaks the steady line,
A vector born of mass and change, twisting space and time.
I am needed to distort, to alter, or to bend,
Yet if my rivals equal me, all variations end.
I can operate through touch, or bridge a vast abyss,
Without my hidden, spectral hand, no orbit could exist.
Force
I am the weakest of the four, yet I hold the cosmic key.
I curve the path of blinding light, though invisible to see.
The grandest giant bows to me, collapsed into a dot,
While the smallest atom ignores my pull, as if I matter not.
I gather dust to forge a star, then trap its dying breath,
A silent architect of life, a heavy hand in death.
What am I?
Gravity
I trace your steps, yet I do not care where you roam.
You can wander ten miles, but I say you stayed home.
I disregard paths, for I only fly straight,
Connecting your launch to your ultimate state.
I am nothing to sound, but to water, a rise,
And the short-sighted arrow that cuts through the skies.
What am I?
